If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Analysis Note
硫酸塩含量 - 硫酸塩は存在する主要なイオン基であるため、純度の指標として使用されます。
ゲル強度 - ゲルを破壊するためにゲルに加えなければならない力。
ゲル化点 - アガロース水溶液が冷えてゲルが生成する温度。アガロース溶液は、液体からゲルへの転移時にヒステリシスを示します。すなわち、それらのゲル化点は融解温度と同じではありません。
電気浸透（EEO）- ゲルの中を通り抜ける液体の動き。アガロースゲルのアニオン基はマトリックスに固定されて動けませんが、解離できるカウンターカチオンはマトリックスのカソードに向かって移動するため、EEOが起こります。通常、生体高分子の電気泳動の動きはアノードに向かうため、EEOは内部対流のために分離を乱す場合があります。

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
